该程序本质上是一个数字猜测游戏,它将猜测存储并排序到arraylist中,并在您正确猜测后显示平均值、最低猜测值、正确猜测的索引数组、平均值和转换后的华氏温度。它介于9和40之间,因为作业指定了40和我学生ID上的最高数字。另外,当我可以简单地将它们放在一个班级中时,不必要的班级数量的原因也是作业规格错误

我遇到的麻烦是在arraylist中存储温度猜测,无论正确与否。我相信我已经在构造函数中正确初始化了arraylist,但我不确定如何或在何处从jTextField捕获猜测。一旦我明白了这一点,我就可以合并我为显示结果编写的其他方法,并完成此任务

再一次,我为我的一般新手性道歉,任何帮助都将不胜感激

1.首先创建一个
Pojo
来存储玩家的所有数据

例如

public class Player{

    int prompt1;
    int prompt2;
    int userInput;
    String comment;
    int restart;

  }
2.然后将它们存储在
ArrayList

///////////Edited///////////////strong>

public class Player{

        int prompt1;
        int prompt2;
        int userInput;
        String comment;
        int restart;

    public Player(int p1, int p2, int usInput, String c, int res){

       this.prompt1 = p1;
       this.prompt2 = p2;
       this.userInput = usInput;
       this.comment = c;
       this.restart = res ;


    }
}

现在假设这个玩家有4个属性,比如温度输入、姓名、年龄、分数……等等,有N个玩家在玩这个游戏。那么你应该使用Pojo和集合(即列表、集合、地图)

现在…从另一节课上应该是这样的

public class Test{


public static void main(String[] args){

        ArrayList<Player> pList = new ArrayList<Player>();

       String name = jName.getText().toString();
       long score = Long.parseLong(jScore.getText().toString());
       int age =  Integer.parseInt(jAge.getText().toString());
       int gTemp = Integer.parseInt(jTemp.getText().toString());


       pList.add(new Player(gTemp, name, age, score));


   }


}
公共类测试{

ArrayList pList=新的ArrayList();
String name=jName.getText().toString();
long score=long.parseLong(jScore.getText().toString());
int age=Integer.parseInt(j
public class Player{

    int guessTemp;
    String name;
    int age;
    long score;


    public Player(int gTemp, int name, int age, int score){

      this.guessTemp = gTemp;
      this.name = name;
      this.age = age;
      this.score = score;
    }

   public int getGuessTemp() {
        return guessTemp;
    }
    public void setGuessTemp(int guessTemp) {
        this.guessTemp = guessTemp;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public long getScore() {
        return score;
    }
    public void setScore(long score) {
        this.score = score;
    }


}
public class Test{


public static void main(String[] args){

        ArrayList<Player> pList = new ArrayList<Player>();

       String name = jName.getText().toString();
       long score = Long.parseLong(jScore.getText().toString());
       int age =  Integer.parseInt(jAge.getText().toString());
       int gTemp = Integer.parseInt(jTemp.getText().toString());


       pList.add(new Player(gTemp, name, age, score));


   }


}
